Fatty liver disease is often referred to as a “silent” condition because it can develop quietly without noticeable symptoms. Millions of people may be living with this disease without even knowing it. Left unchecked, it can progress and lead to serious liver damage. The good news? If detected early, fatty liver disease is often reversible through lifestyle changes.

Below are eight often-overlooked signs that may indicate the presence of fatty liver disease—especially important for older adults or those managing weight, diet, or blood sugar.

What Is Fatty Liver Disease?

Fatty liver disease occurs when fat accumulates in liver cells. It comes in two main types:

• Non-alcoholic fatty liver disease (NAFLD): Common in people who drink little to no alcohol, especially those with obesity, diabetes, or high cholesterol.

• Alcohol-related liver disease (ALD): Caused by long-term excessive alcohol consumption.

According to the American Liver Foundation, about 1 in 3 adults in the U.S. has NAFLD, with rising cases among people over 50.

1. Unexplained Fatigue

Feeling constantly tired despite getting enough sleep? This could be one of the earliest and most common signs.

• The fatigue isn’t relieved by naps or caffeine.

• It feels more like persistent low energy or heaviness.

• A struggling liver can impair metabolism, leading to reduced energy.

2. Discomfort in the Upper Right Abdomen

A dull ache or pressure just below the right rib cage might indicate liver stress.

• It’s not typically sharp or severe.

• May worsen after eating high-fat meals.

• Bring it up with your doctor if it’s a recurring issue.

3. Sudden Weight Gain (Especially Around the Belly)

Unexpected weight gain, particularly around the midsection, could be a signal.

• Fatty liver can impair the body’s ability to process fat and sugar.

• This often results in more abdominal fat.

• Belly fat is closely linked to metabolic syndrome, which commonly overlaps with fatty liver disease.

4. Brain Fog or Trouble Concentrating

Difficulty remembering things or staying focused could be connected to liver health.

• Toxins may remain in the bloodstream longer due to reduced liver function.

• This can subtly impact memory and cognitive clarity.

• If you frequently feel “off,” don’t ignore it.

5. Elevated Liver Enzymes

Fatty liver is often discovered during routine blood tests.

• Doctors may notice high ALT or AST enzyme levels.

• You might feel fine but your liver may already be affected.

• Ask your doctor to explain your liver enzyme results.

6. Darkened Patches of Skin

Velvety dark patches around the neck, underarms, or groin may signal insulin resistance.

• This condition is known as acanthosis nigricans.

• It’s often seen alongside fatty liver, especially in people with prediabetes or type 2 diabetes.

• Also watch for small skin tags in those areas.

---

7. Nausea or Digestive Discomfort After Eating

Feeling bloated or slightly nauseous after meals could be more than indigestion.

• Fatty liver can reduce bile production, making fat digestion harder.

• This discomfort is more common after fatty or fried foods.

---

8. Swollen Belly or Legs (Later Stages)

In advanced cases, fluid buildup (ascites in the abdomen or edema in the legs) may occur.

• Legs may feel heavy or appear puffy, especially around the ankles.

• Belly swelling may be firm and persistent.

• These are serious signs and warrant immediate medical attention.

Who’s at Risk?

Several factors increase the risk of fatty liver disease:

• Being overweight or obese

• Having type 2 diabetes or prediabetes

• High cholesterol or triglycerides

• Inactive lifestyle

• Poor sleep or sleep apnea

• Frequent consumption of sugary or processed foods

Even without these, aging alone can increase risk.

Supporting Liver Health Naturally

The liver is remarkably resilient and can heal if given proper support:

1. Eat a liver-friendly diet:

• Focus on leafy greens, fruits, whole grains

• Avoid trans fats, sugary drinks, and processed snacks

• Stay hydrated with water

2. Exercise regularly:

• Aim for 30 minutes of movement most days

• Activities like walking, swimming, or resistance training are helpful

3. Prioritize good sleep:

• Aim for consistent, quality sleep

• Poor sleep can worsen insulin resistance and weight gain

4. Monitor medications:

• Some over-the-counter drugs, like acetaminophen, can stress the liver

• Review your medication list with your doctor

5. Limit alcohol:

• Even moderate consumption can worsen liver issues

When to Talk to Your Doctor

If you have one or more of the signs listed above—or risk factors—discuss liver health with your healthcare provider. They may recommend:

• Liver function tests (LFT)

• Imaging tests like ultrasound or FibroScan

• Referral to a liver specialist

Early detection is key to preventing long-term damage.
